Mean, Median, and Mode

Learning how to calculate Mean, Median, and Mode.

Mean

• Also Known as Average

• It is where you add up the values and divide the sum of value by how many values.

• Eg. 1,1,2,3,4,7. The mean will be 1+1+2+3+4+7=18,

   $18\div6$ =3

Median

• This is where you find the middle number of a set of numbers that is in order.

• Eg. 1,2,3,5,7 the median is 3

• Eg. 1,1,2,3,4,7 (since there is an even number of values you will have to add two of the numbers that is in the middle an divide it by 2) which is 2.5

Mode

• This is where you find the number or numbers that is recurring (repeated) the most

• Eg. 1,1,2,3,4,7,7. The Mode is 1 & 7
